Wheel Collider always flip out the car

I use same code with Andrew Gotow tutorial. Everytime i turn left the car was turn right and then flip up. Here’s the video http://youtu.be/IV_BIIi4zHg

thanks for any help

set the center of mass to the center of the vehicle, and make sure that the car has regidbody with around 1000 to 3000 weight.

I didn’t watch the tutorial video. However, I have 2 suggestions.

  • Try increasing the gravity on your rigibody.

  • Try using Vector3.Project.
    I personally use it, in my jet simulator, my plane used to drift after I banked or turned, and I added these vectors on the opposite directions in order to prevent the drift and to maintain the turn.
